Woken up this morning by the wife, who couldn't turn the ignition key to start a 2002 blazer. Ran fine last night when she parked it, but now the key will not turn when inserted in the ignition and the transmission is locked in Park. It's parked on a level surface (no torque lock), and the steering wheel is also locked. Key has been fully inserted, and have tried turning the wheel hard left then right as manual recommends, but no joy. Cannot shift car into neutral either- whole steering column is locked.
Any advice?
